Also, I've put in /etc/profile.local the line "ulimit -n 8192", hoping it will help.

WARNING: If you are unix the JVM uses the select() then increasing the ulimit above the default 1024 maybe dangerous. This is because the default select() usage set only allocates enough memory for 1024 descriptors in its bitmap. This can result in the bitmap modification functions FD_SET() from scribbling over memory off the end of the memory allocation.

It is also necessary to audit all system libraries that the JVM loads and uses during the course of running, everything that waits for non-blocking IO must be audited.



If you are unix take a look at "ls -l /proc/$pid/fd/" to see where all your file descriptors are going.
